COMBINED BARREL VENT AND BUSHING.

SPECIFICATION forming part of Letters Patent No. 587,613, dated August3, 1897. Application filed November 25, 1896. Serial No. 613,359. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, FRANK W. SCHLAGER, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new Improvement in aCombined Barrel Vent and Bushing; and I do hereby declare the following,when taken in connection with the accompanying drawings and the lettersof reference marked thereon, to be a full, clear,

to and exact description of the same, and which said drawings constitutepart of this specification, and represent, in

Figure 1, a side view of a combined barrel vent and bushing constructedin accordance I 5 with my invention; Fig. 2, a vertical central sectionof the same; Fig. 3, a detached view of the lower end of the vent-pipe.

This invention relates to an improvement in a combined barrel vent andbushing such as is commonly used with barrels of ale and beer, and sothat a supply of air maybe forced into the barrel from any convenientpoint, the

act of coupling the vent to the bushing opening the valve in the barrel,and so that air 2 5 may be forced inward, yet prevent the escape of theair from the barrel, the object of the invention being to provide aneffective valve and convenient means for coupling the ventpipe to thebung; and it consists in the con- 0 struction, as hereinafter described,and particularly recited in the claim.

A represents the bushing, which is circular and provided with threads afor engagement with the barrel in the usual manner. Through the end ofthe bushing and so as to project upwardly therein and downwardly belowthe bushing is a cylinder B, partially closed at its lower end by aplate C, having a central opening 0, around which is a series ofopenings (Z,

and below the openings depends an annular rib e. Extending through thecylinder is a spindle E, the lower end of which is threaded and extendsthrough the opening 0 and receives a packing-washer F, of rubber orother 5 suitable material, over which is placed a cap G, which issecured to the end of the spindle by a nut g. Around the spindle in thecylinder is a spring H, located between the plates C and stops I, thetendency of the spring being to lift the washer at the lower end of thespindle upward against and so as to close the lower end of the cylinder.

J is an air-pipe adapted to be connected from any suitable source ofsupply and is formed with a flange K, which may be seated 5 5 upon awasher L within the bushing A, and from the center of the pipe depends ahollow stem M, closed at its lower end and formed with side ports oropenings N, said stem being adapted to bear upon the upper end of 6a thespindle E when the pipe is forced downward by a coupling member 0, whichcoupling member 0 is provided with a handle P and formed with threads Q,adapted to engage'with the threads R, formed in the inner wall at theupper end of the bushing A. The lower end of the coupling is recessed toreceive a shoulder J, formed at the lower end of the air-pipe J, whichshoulder is adapted to form a tight joint between the coupling memberand air-couplin g. Surrounding the stem M is a sleeve S, of rubber,which closes the ports N, the said sleeve having a slot 3 locatedbetween the ports N.

lVhen it is desired to admit or force air into the barrel, the couplingmember 0 is turned into the bushing A, which presses the stem Mdownward, whereby the spindle E is forced downward and opens the lowerend of the cylinder. vVhen thus opened, air may be forced downwardthrough the pipe J and will escape through the openings N and expand therubber sleeve S, so as to allow the air toescape through the slot 5,while if the force of air be removed the sleeve S closes the opening sand prevents the escape of air from the barrel. Vhen the coupling memberis removed. to detach the air-pipe, the spring I-I acts to close thevalve at the lower end of the cylinder and so that the parts are brought0 into position for action by the act of coupling the air-pipe to thebung.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is v 9 5 In a combined vent andbushing, the combination with the bushing supporting a cylinder, a valveadapted to close the lower end 10 upper end of the bushing, whereby saidstein is forced to press the spindle downward, substantially asdescribed.

In testimony whereof I have signed this specification in the presence-oftwo subscribing witnesses.
